  • Well Made!
Size: 0 - 6" Range Style: 6-Inch Digital Caliper
Can’t believe how much better this is than my old cheap set. Should have spent more years ago. Would have saved me a lot of guess work, and trouble converting measurements. Much more accurate as well.

  • Comparable to expensive measuring tools.
Size: 0 - 6" Range Style: 6-Inch Digital Caliper
More dependable than the multiples I have. This one is very precise and works as it should. It is worth the several extra dollars when compared to the poor quality of others in retail stores found locally.

  • Nice set for the price
Size: 0 - 6" Range Style: 6-Inch Digital Caliper
First off for the price point this set is made very durable and very smooth to use. Second the slide is made out of stainless and the display is easy to see and change. Lastly General made a very sound caliper and would highly recommend if you are in the market for a pair.

  • General Tools digital caliper
Size: 0 - 6" Range Style: 6-Inch Digital Caliper
Easy to use, readings, and accurate enough for my needs. Though I was under the impression that I was purchasing a USA made tool, but it's not. Still, for the cost, I'm good with it. Handy tool to have for different measurments.👍

  • outstanding quality
Size: 0 - 6" Range Style: 6-Inch Digital Caliper
Had several calipers over the years and they weren't anywhere close to the quality of this heavy stainless steel unit, easy to open and close with precise movement, even the battery cover heavy and set in place with a set screw. I also love the 3 modes of units, really like the fraction display. My prior one I bought at a woodcrafting store and was told it was quality but when i went to actually use it one of the plastic operating buttons had fell out and the unit would no longer power on. I also love that it comes with a hard case as these are somewhat delicate and need some level of protection to ensure they remain accurate. In fairness, I used this one once to measure something the day I received it but can spot quality when I see it. ... show more
